WebJul 10, 2016 · The values in the matrix are counts of sequencing reads (in the case of single-end sequencing) or fragments (for paired-end sequencing). This is important for the count-based statistical models, e.g. DESeq2 or edgeR, as only the counts allow assessing the measurement precision correctly.

WebWhat I need to do is to compute the average excluding (set to NaN?), the values in each sub matrix falling outside the upper and lower limits, namely those grater than the mean+standard deviation of the 3x3 matrix and those smaller than the mean-standard deviation of the 3x3 matrix, respectively. Depending on the library preparation method used, the RNA sequences (also referred to as reads or tags), will be derived either from the 3’ ends (or 5’ ends) of the transcripts (10X Genomics, CEL-seq2, Drop-seq, inDrops) or from full-length transcripts (Smart-seq).
